TO PERFECTION PACKAGE SEALER COMFANY, A CORPORATION OF TEXASGUMMED-TAPE-DISPENSING MACHINE Application filed March 4, 1927. Serial110. 172,712.

This invention relates to gummedtape dispensing machines and has specialreference to improvements in the types of gummed tape dispensingmachines for which a patent on June 13, 1926, Number 1,592,451.

One important object of the invention is to provide an improved.arrangement of gummed tape dispensing machine wherein 1 the tape isnormally prevented from engaging with the moistener by certain novelarrangements of delivery means.

A second important object of the invention is to provide animprovedarrangement of tape may be fed forward from the machine to adesired extent without touching the tape with the fingers. p

A third important object .of the invention is to provide an improvedform of tape feeding mechanism so combined with tape cutting mechanismthat the same manual means which operates the feeding mechanism by onemovement may be caused to actuate the tape severing means by a secondmovement. I A fourth important object of the invention is to provide anovel and improved arrangement of means whereby the tape will be con-.

stantly engaged frictionally by the delivery mechanism.

A fifth important object of the invention is to provide improved meansfor supporting rolls of tape of different widths.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations. of'parts hereinafter fully described,illustrated in the accompanying drawings and specifically claimed.

Figure 18 isa perspective view of this modfrom the side opposite. Figisa section on the line 6-6 of .a water tank and the rear of this casingis covered by a closure 11 having flanges 12 extending over the sides ofthe casing 10. Extending longitudinally of this closure the metal isdepressed centrally to form a-trough like structure 13 wherein may beslid, from the rear end of the machine, a plate 14 having downwardlyturned flanges 15 at its sides to hold the body of the plate flushwiththe surface of the closure 11. Mounted toward the forward end of theclosure is a pair of L- shaped brackets 16 and in the upper end ofopenings in the lip 36 and base plate 23.

these brackets is journalled the shaft 17, the journal ends of thisshaft projecting laterally beyond the brackets on each side andpreferably being covered with friction rings 18 of rubber or the like.This shaft 17 carries a tape feeding roller 19 which contacts with aplate 20 supported in a well 21 formed in the slide 14. The plate 20 ispressed upwardly toward the roller 19 by suitable springs 22 so thatpaper or gummed tape passing between the feed roller 19 and the presserplate 29 will be forced frictionally against the roller 19. At the rearend of the machine there is provided a roll support which includes abase plate 23 extending transversely of them achme and provided at eachside with downwardly and laterally extending flanges 24 secured to theclosure 11 by screws 25 so that the base plate 23 is held in positionthereby. At each side of the center of the machine this base plate isprovided with a series of spaced slots 26 and supported on the baseplate are stamiards 27 each having a Z-shaped foot 28 so that therespective standard may have its foot engaged in any one of the slots 26and be held in an upright position. In order to prevent accidentaltilting and disengagement of the standards 27 there is provided beneaththe base plate 23 a spring presser plate 29 which is urged upwardly bysprings 30 surrounding guide pins 31 as shown. The plate 29 engages theunder sides of the feet 28 and thus holds the standards 27 fromaccidental tilting.

These standards are provided with slots 32 for the reception of thecenter pin 33 of a roll 34 of gummed tape. At the end of the slide 14there is provided an'upwardly extending flange 35 which is bent toextend forwardly over the plate 23 as at 36 and is held from movement bypins 37 passing through suitapgle .7 this means the slide is preventedfrom accidental movement relative to the closure 11.

Extending upwardly from the top of the closure on each side thereof is aseries of brackets 38 and to the upper end of each series of bracketsthere is secured an angle guide bar 39, the brackets being secured tothe vertical leg of this guide bar while the horizontal legs projecttoward each other. Seated in the angles of guide bars 39 are other anglebars 40 which are preferably termed the pull bars. Connecting the bars40 at the rear end is a tie rod 41 the ends of which project throughslots 42 formed in the vertical legs of the members 39. The horizontalleg of each member 39 is provided with a series of stop'receivingopenings 43 spaced adjacent the edge and these openings are adapted toreceive the downwardly extending legs 44 of a stop bar 45 which extendsacross the'machine. The legs 44 extend downwardly far enough to be en-.gaged by the tie rod 41 upon movement of the angles 40 forwardly and bypositioning order to normally hold these angles 40 inv rearward positionthere is provided at each side of the device a tension spring 46 one endof which 18 connected to the bar 41 and the rear end of which is securedto a lug 47 formed on the vertical leg of the respective angle The anglebars 40 pass beneath the journal ends of the shafts 17 and arepreferably provided on their horizontal legs each with a friction strip48 engaging the friction band 18. The ends of the bars 40 are connectedby a hand grip 49 so that they can be drawn forwardly together.Extending upwardly from the slide 14 are lugs 50 which support a guidebar or roller 51 and the gummed tape is led from the roll 34 along thepath 52 beneath this roller 51 and between the feed roller 1.9 andpresser plate 20. The angle bars -10 have an up and down motion at theirfront and "may be lifted to obtain firm engagement between the frictionmembers 48 and 18. IVhen thus engaged and drawn forward by the hand grip49 the. shaft 17. and consequently the feed roller 19 will be rotatedand the gummed tape fed forwardly beneath this feed roller. It is to beobserved that the rolls of gummed tape in some instances have the gummedside inwardly of each rear end and in other instances outwardly. In theoperation of the machine with inwardly gummed tape the tape is fed offthe upper part of the roll as shown in Figure l but, if the tape begummed on the outer side it will naturally be fed olf of the lowerpartof the roll. Obviously, the amount of tape fed off the roll will beregulated by the position of the stop bar 45 and it will also be obviousthat because the feed roll 19 is of larger diameter than the frictionbands 18 the amount of tape fed forwardly will be in the same ratio tothe forward movement of the angle bars 40, which may be termed forconvenience I feed bars, as the diameters of the friction band 18 andfeed roller 19. Forwardly of the feed roller the sides of the casing 10are provided with notches 53 wherein is seated a knife frame 54 carryingat each end a pin 55. These pins support a stationary knife blade 56 andon one of these pins, between the blade 56and frame 54 is pivoted, anoscillating knife blade 57 which is normally held slightly raised bymeans of the spring 58'. Pivoted centrally of the knifeblade 57 andextending upwardly between guide lugs 58 is an arm 59 having laterallyextending fingers 60 which lie. beneath the horizontal legs of the feedbars 40. The gunnned tape passes between these blades 56 and/57 and uponthe feed bars being drawn out the forward end of these bars may bedepressed So that the upper blade 57 is swung down scissors fashionacross the blade 56 and the tape severed. J ustto the rear of theseknife blades there is provided on the slide upstandin lugs 61 whichcarry a cross bar 62 on whic are slidably m unted' short sleeves 63carrying guide fingers 64 having'downwardly turned ends 65 which arearranged to pass through selected openings 66 in a guide plate 67supported in spaced'relation to the to of the slide 20, comics ondingopenings bein also made in the side for these ends. y this arrangementguide means is afforded for the forward end of the tape. In frontof-theblades there is provided a lower guide plate 68 preferably ofspring-metal and having an upturned forward end provided with sideguide; lugs 69.

Spaced above this is an upper guide plate 7 0 w iich'has a. forward edge71 which may be serrated as shownin Figure 9 or may be withoutserrations as shown in Figure 2, In

some instances it is preferred, as shown in the form for use beneath thecounter, to use these serrations since no knife is used in this form. Inother instances, where a knife is used, the serrations may be omitted.

The moistening device is indicated in general at 72 and may be the sametype as shown in my copending application above referred,

to but it is to be noted that the moistening device is so positionedthat normally the extremity of the tape which projects from be tween theplates 68 and 70 does not contact with the moistening device but ma bepressed down thereon as the tape is fed off.

In the modified form of the invention adapted for support beneath acounter or the like the casing is rovided with L-shaped hangers 72which-engage in guide bars 73 secured beneath the counter and there maybe either two individual guide bars as shown in Figure 14 or there maybe a single plate 74 having its edges bent to form channels 7 5.

- In this form the paper roll hangs downwardly, this part of theinvention being simply inverted. In this form the knife blades areomitted, dependence being bad on the serrated forward edge of the upperguide 7 O.

In the modified form of moistening device the body of the device isformed of stamped metal and consists of a body plate 76 having pivotlugs 77 projecting from the sides and also having rearwardly extendingweight carrying arms 7 8 stamped from the sheet metal and overthemoistener- The moistened strip of tape is then raised and torn offagainst the I front edgfi of the member 7 O.

. There as thus been" provided a simple and eflici'ent device of thekind described and for the purpose specified.

It is obvious that'minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. It is not, therefore, desired to confineathe invention to theexact form herein Show? and described, but it is desired to include alsuch as properly come within the scope claimed.
